WebAbstract: An HPLC assay with fluorometric detection has been developed that is sensitive enough to measure simultaneously endogenous levels of tryptophan, serotonin (5-hydroxytryptamine, or 5-HT), and 5-hydroxyindoleacetic acid (5-HIAA) inside synaptosomes as well as that released into the incubation medium. Using this assay, we have observed … WebL-Tryptophan-13C11,15N2 ≥99 atom %, ≥98% (CP); CAS Number: 202406-50-6; Synonyms: L-Tryptophan-ul-13C,15N; find Sigma-Aldrich-574597 MSDS, related peer-reviewed papers, technical documents, similar products & more at Sigma-Aldrich WebPostprandial somnolence (colloquially known as food coma, after-dinner dip, and postprandial sleep, or by the African-American Vernacular English term the itis [1]) is a normal state of drowsiness or lassitude following a meal.
